HENRY WENNEBORG, JR., OF SPRINGFIELD, ILLINOIS, ASSIGNOR OF ONE-HALF TO CHARLES A. ANDERSON, 0F SPRINGFIELD, ILLINOIS.

COMBINATION-TOOL.

Specification of Letters Patent.

Patented N0v.'21, 1911.

To all 'whom 'it may concern:

Be it known that I, HENRY WENNEBORG, Jr., a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented a new and useful Combination-Tool, of which the following is such a full, clear, and exact de scription as will enable others skilled in the art to make and use my said invention.

This invention relates to devices of that kind which embody in a singletool a plurality of instrumentalities adapted for different uses.

The purposes of the invention are to provide a combination tool capable of use in different positions, as a boring or drilling tool; as a bench clamp; and as a vise or sawclamp, said tool being of light and strong construction and easily portable, and effective for all the uses set forth.

With these ends in view the invention consists in the novel features of construction and combinations of parts shown in the anneXed drawings and hereinafter particularly described and finally recited in the claims.

Figure 1 is a side elevation of the complete tool, some of the parts being shown in section to more clearly illustrate the interior construction; Fig. 2 is a transverse sec-v tion on the line fv. o. of Fig. 1; Fig. 3 is a side elevation of the tool as it appears when the saw-clamps are removed, some of the parts being shown in section; Fig. 4 is a vertical section on the line W. W. of Fig. 1; Fig. is a partial isometric view of one of the clamping jaws; Fig. 6 is an isometric view of the head of the drill shaft; Fig. 7 is a View of one of the screws which connect the clamping jaws with the tail stock and the pivoted jaw respectively, and Fig. 8 is a transverse section on the line X. X. of Fig. 3.

Similar reference numerals and characters designate like parts in the several views.

The tool is preferably constructed of pressed steel, but other suitable material, such as malleable casting, may be used.

The frame or main structure 1, comprises a bar of I-shaped cross section, having its ends bent approximately at a rightangle to form a head stock 2 and a tail stock 3 integral with the body of the bar, as clearly shown in Figs. 1 and 3. The head stock 2 has a boss 2a internally screw-threaded to accommodate the thread of the tubular screw 4 turningin said boss. The upper part 4 of the tube 4 is preferably square.

A hand wheel 5 has a square hub 5a fitting on the square part 4b of the sleeve 4. At the lower end of the sleeve 4 is an enlargement 4a, strengthening that part of the sleeve.

The tailstock 3 has in its sides longitudinal channels 3a respectively accommodating the legs 6a of the dog 6. The dog 6 has a screw-threaded member 6b adapted to extend through the bar 7.

To facilitate the placing of the dog on the frame l, part of the outer flange of the head stock 2 is cut away, as at 1a, to permit the legs of the dog to pass the flange and travel in the channels 1b and 3a.

A nut 3 its on the screw of the member 6'D and connects the dog with the bar 7.

A screw 9 having a square head 9a screws into and ext-ends through the bar 7 andl serves to clamp the bar 7 against a stationary support A, to hold the tool in a vertical position, as shown in Fig. 1, or the dog may be moved and placed on the frame 1 in such position that the same bar 7 and screw 9 may be used to securely connect the tool in a horizontal position on a stationary support A', as shown in Fig. 3, as hereinafter more fully described.

A shaft 12 fits and turns within the bore of the tube 4, and has at one end a head 12a provided with a tool socket 12b, and having a semi-globular or rounded enlargement 12, shown in detail in Fig. 6.

A square nut13 is secured at one end of the shaft 12 and bears against the outer end of the hub 5a of the hand wheel 5. A crank' 14 has a square socket 14a adapted to fit on the nuts 13 and 9a or the hub 5a, or the nut 8,

or the heads of the bolts 10 and 10. The bolt 10 is shown in detail in Fig. 7 and the bolt 10 is just like it.

A set screw 14b serves to secure the crank on the hub 5a, as shown in Fig. 1, or to secure it on the hub 5a and the nut 13; or to secure it on the nut 13 alone; as indicated 3b in line with the axis of the shaft 12 and accommodating the screw 10 and a longitudinal slot 3d, the use of which is hereinafter explained.

The block 15 has a hook-member 15a, standards 15", and a downwardly extending member 15C. The member 15a of the block 15 hooks under the flange of the frame 1, and the block is slidable and may be set in different positions on the frame. A screw 1G serves to secure the block in the different positions in which it may be set. The screw has a conical end formed to bear on the edge of the flange to hold the block firmly against the upper side of the frame.

The jaw 17, which will be hereinafter referred to as the movable jaw, is connected with the block 15 by a pivot 17a, so that the jaw will oscillate on the block.

The jaw 17 has integral members 17 separated by a space 17 b. It also has a circular depression 17 C in line with the shaft 12 and adapted to accommodate the semi-globular enlargement 12C of the head 12, so that the jaw will have limited universal movement on the end of the head. The jaw 17 also has a central screw-threaded hole 17d accommodating the screw 10.

A plate 1S having a central hole smaller than the circumference of the enlargement 12's and somewhat larger than the circumference of the head 12a, is connected with the jaw 17 by screws 19.

Springs 20 surround the screws 19 and act to hold the plate 18 against the jaw 17, to form a yielding connection between the jaw and the head, such that the jaw will have limited universal movement without lost motion between the movable parts.

The clamp or vise jaws 21 and 21 are exactly alike, so a description of one will suffice for both.

The jaw 21 has a hole 21a accommodating the screw 10 or 10, connecting the vise jaw with the movable aw 17, or the tail stock 3, as the case may be. It also has an inwardly extending member 21b iitting in the slot 3d of the tail stock, or in the space 17 b between the members 17 of the movable jaw, to prevent lateral movement of the vise jaw; and a flat face 21e, co-acting with a similar face of the complemental jaw to hold a saw or other article between the aws.

The holes 17d and 3b are both in line with the shaft 12 in order that when the clamping jaws 21 and 21 are removed a bit or drill seated in the socket 12D may extend through the hole 17 1 to act upon the article held between the movable jaw 17 and the tail stock 3, and also in order that when a hole is bored or drilled through the article, the projecting end of the bit may extend into the hole 3b, thus avoiding injury to the point of the bit.

1n case the sides of the article held between `the tail stock 3 and the jaw 17 are not parallel, the ball and socket connection of the jaw 17 with the head 12 will permit the jaw to yield to conform to the surface with which it contacts.

To move the jaw 17 quickly toward or away from the tail stock the thumb screw 16 will be loosened, the crank 14 will be secured on the hub 5a and will be turned to cause the sleeve 4 to slide the jaw 17 and the block 15 to the desired position, and the thumb screw will then be tightened to secure the block in the position in which it has been placed.

The several modes of using the tool are as follows: The tool will be secured on a suitable support in a vertical position or a horizontal position, as may be more convenient for the contemplated use. 1f a saw is to be sharpened it will be placed between the jaws 21 and 21 and the handle 5 will be turned to move the jaw 21 to firmly clamp the saw between the jaws.

If it be desired to bore wood the screws 10 and 10 and the jaws 21 and 21 will be removed. The article to be bored will be placed against the inner face of the tail stock 3 and the crank 14 will be secured on the nut 13 and the hub 5a of the wheel 5 and a suitable bit will be placed in the socket 12b and the crank 14 will then be turned to rotate the tubular screw 4 to cause the bit to bore rapidly through the wood.

When the bar 7 is in the position indicated by dotted lines in Fig. 3, the article A to be drilled may be held between the bar 7 and the tail stock 3, and the drill operating thereon will extend through the holes 17 d and 3b.

To drill a hole in metal the procedure will be the same, except that slower feed of the tool to the work will be necessary. To effect this slower feed the crank 14 will be secured on the nut 13 to rotate the shaft 12 and the wheel 5 will be turned by hand from time to time, as may be necessary, to produce the desired feed. 4

1f it be desired to drill a series of holes through a plate which cannot be conveniently placed on or against the face of the tail stock, the plate will be placed under or against the back of the tail stock and the tool be held firmly against the plate by any suitable means, and the first hole will be drilled. After the drilling of the first hole a bolt will be placed in the drilled hole and through the slot- 3d of the tail stock and the nut will be tightened to clamp the article against the under side or back of the tail stock in position for boring the next hole; the nut will then be loosened and the article moved a distance equal to the desired distance between the holes and the nut will be tightened to again secure the plate, and this may be repeated until the bolt connecting essary foridrilling the succeeding holes until the bolt again traverses the length of the slot; and this will be repeated as often as may be desired.

For grinding -or polishing, the mandrel of the wheel will be placed in the socket 12";

4the crank 14 will be secured on the nut 13 and will be turned to cause the shaft 12 to rotate the grinding wheel.`

In gluing together wood work, or the like, the tool may be used in two different ways, namely: The article to be glued may be placed between the jaws 21 and 21 and the hand wheel 5 be turned to cause the jaw 21 to move and clamp the article between the jaws; or the nuts 8 and 9'n1 may be loosened to adjust the bar 7 to hold the article between the bar 7 and the tail stock 8, and the screw 9a will be tightened to clamp the bar 7 on the article.

It will be observed that the socket 14a of the crank 14 iits on the hub 5a, or the nut 13, or the nut 8, or the head of the screw 9a,

or the head of the screw 10, or the head of the screw 10', and is therefore the only instrument needed for adjusting the tool for all the different uses.
